v[To all whom t may concern:

"roN Wool), a citizen of the United States,

residing at Petros, in the county of Morgan and State of Tennessee, have invented a new and useful Improvement in Car-Gouplings, of which the following is a specification, reference being had to the accompanying drawing.

y improvement relates particularly to couplings for cars which are to be turned in dumping structures for the discharge of loads held by the cars.

rIhe object of the invention is to provide a coupling structure comprising a link and a coupling pin for securing the link to the draw bar or similar member, the structure comprising also means for retaining the pin in position when the car is turned far enough for discharging its load by gravity.

In the accompanying drawings,

Figure l is a plan showing a part of one end of a car and a draw bar projecting from said end, and a link and a pin applied to said draw bar.

Fig. 2 is a sectional elevation 2 2, of Fig. 1.

Fig. 3 is a section on the line, 3-3, of Fig. 1, looking toward the left.

Fig. 4 is a plan similar to Fig. l, the car having a buifer below the draw bar.

Fig. 5 is a section on the line, 5-5, of Fig. 4, looking in the direction of the arrow.

Fig. 6 is a section on the line, 6-6, of Figs. 4 and 5, looking in the direction of the arrow.

Referring first to Figs. l, 2 and 3, A is a portion of one end of a car body. C is the outer end or head of the draw bar projecting outward from the car. D is the coupling pin. E is the link.

The draw bar, C, has the usual horizontal recess or chamber, C1, of proper form to receive one end of the ordinary link, E, when the latter is in the horizontal position. The draw bar also has the ordinary upright pin socket, C2, extending through the middle of the draw bar and cutting the recess'or chamber, C1, in position to receive the pin, D, said pin extending through the link, E.

Said pin is of ordinary form, excepting that the annular shoulder, D1, which rests upon the upper face of the draw bar and thus limits the downward movement of the on the line,

pin is provided with an upper 'horizontal face, D2. Furthermore, the diameter of said pin is made less than the diameter of the pin socket, C2, in order that the pin may be moved sidewise manually to effect this engagement from the pin-stop, C3. In the form shown in Figs. l and 2, said pinstop is cast integral with the draw bar, but it may be applied in any suitable manner.

Said stop is so located on the draw bar as to be below the pin when the car is turned by discharging its load; and said stop extends far enough toward the pin socket, C2, to cause the stop to extend across the face, D2, when the car has been turned for discharging, the pin having moved by gravity against the portion of the wall of the pin socket, C2, which is adjacent said stop.

Under this condition, the pin can not slide out of the pin socket, although the car has turned far enough to partially invert the pin and cause the latter to tend to slide by gravity from said socket.

In Fig. 4 a bu'er, B, extends forward from the car body, A, and beneath the draw bar, C. The outer end of the draw bar does not have the recess, C1, of Fig. 2, but there is a space between the draw bar and the buffer, B, to receive the link, E. The pin socket, C2, extends through the draw bar and the buffer, B. 'Ihe stop, C3, is seated on the buffer beside the draw bar and extends upward and over the latter into position to engage the pin in the manner already described with reference to Figs, l, 2 and 3. Said stop is firmly secured to the bu'er by bolts, B1, extending through the base of the stop into the buffer.

I claim as my invention:

l. In a car coupling, a draw bar having a pin socket the upper portion of which is wider than the adjacent diameter of the pin, a pin resting in said socket, and a pin stop located beside said socket on a line parallel to the line of draft and adapted to reach over a portion of said pin to prevent its movement out of said socket, substantially as described.

2. In a car coupling, a draw bar having a pin socket the upper portion of which is wider than the adjacent diameter of the pin, a pin resting in said socket, and a pin stop integral with the draw bar and located beside said socket on a line parallel to the line of draft and adapted to reach over a portion o' sai'd pin to prevent its movement -'out of said socket, substantially as described. Y

8. In a car couplinga draw bar having a pin ysocket the upper portion of Which is Wider than the adjacent diameter of the pin, a pin resting in said socket and having an annular flange resting upon the upper face of the draw bar, and a pin stop located beside said socket on a line parallel to the l0 line of draft and adapted to reach over said annular flange, substantially as described. y

In testimony whereof I have signed my name, this 29th day of November, in year one thousand nine hundred and sixteen.
